PORTABLE FORG E.

QPECIPICATION forming part of Letters Patent N0. 366,469, dated July 12, 1887.

Application filed April 22, 1887.

To all whom it may concern.-

Be it known that I, Mrcrmnr. EHRGOTT, of the city of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Portable Forges, of which the following is a full, clear, and exact description.

My invention relates to an improvement in portable forges, and has for its object to provide a forge which will occupy a minimum amount of space, yet afford a large amount of hearth-room, and wherein the blast may be instantly varied from light to heavy, and wherein the tuyere may be kept clean without disturbing the fire.

The invention consists in the construction and arrangement of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a front elevation of the forge. Fig. 2 is a horizontal section on line as a: of Fig. 1. Fig. 3 is a side elevation, partly broken away and in section. Fig. 4 is a vertical section through the tuyere-iron; and Fig. 5 is a central vertical section on line y y of Fig. 4.

In carrying out the invention the forge is made with a square top, A, provided with an opening, a, in the front, adapted to extend from side to side and from the hearth a nearly to the top, the hearth a, being formed with a spacious central and annular depression, B, as shown in Figs. 2 and 3.

The-base O, which may be either rectangular or circular, is made smaller than the top, and is attached thereto at the lower end of the depressed portion B. Centrally the said base, and near the bottom, at the front, an opening, I), is provided, and above said opening, at one side, also in the front, an aperture, 1), is made.

A tuyere-iron, D, is attached to the under and centrally one side portion of the depression B, a suitable aperture, cl, being made therein to accommodate the upper end of said iron, as shown in Fig. 4.

The tuyere-iron is preferably made circular and tubular, with the aperture cl in the top having upwardly-tapering walls, being of less Serial No. 235,732. (No model.)

diameter than the opening in the body, which opening extends entirely through the iron. In one side of the body a draft-pipe, E, 1s mserted, adapted to project outward through the base, and in the top portion of the tuyereiron, immediately below the opening (1, a tuangular damper, E, is journaled, operatedby a shaft, 0, terminating in a crank, c, which shaft is made to extend through the base a distance outside, as shown in Fig. 5. The corners of the damper E are made round to facilitate turning. It will be thus seen that by a simple turn of the damper the blast may be changed from heavy to light, or vice versa. The shaft 0 is also made to turn in the aperturcd upper end of a bracket, H, which consists of a flat piece of spring metal attached to the side of the tuyere-iron, as shown in Fig. 5, one end of which, extending upward, forms a bearing for the shaft 6, as aforesaid, the other end being bent outward in rectangular form and inward beneath the tuyere, where it 1s bent again outward upon itself, serving as a spring and guide support for a slide, H, operated by ahandle, 71, passing out through the aperture 1) in the base, the said slide belng adapted to dump any ashes that may be delivered from the fire by the angular damper.

It will be observed that by the construction above set forth a forge is obtained having a vast amount of heartlrroom, and wherein all the said room may be utilized, by reasolrof thelarge rectangular front opening; aud,aga1 n, that by means of the peculiar shaped damper the fire may be quickly relieved from dead coal and the said coal readily delivered from the tuyere by the slide H.

The tuyere-iron is preferably held in connection with the under side of the depression in the hearth of the forge by bars 10 and bolts 10, passing through the said depressed surface and clamping said bars in close contact with the flange of the iron. The said bolts do not, however, pass through the flange of the iron.

The uppe r portion of the spring-bracket ll, engaging the collar upon the damper-rod 0, makes an air-tight joint at that point.

The opening I) in the base is purposcd speeiallyv to facilitate the removal of ashes from the forge.

Having thus described my invention, what I claim as new, and desire to secure by Letters in said hearth, provided with an aperture, d, I 5 Patent, isand a base portion, 0, having an uncovered 1. A portable forge having the top thereof front aperture, 2), of the tuyere-iron D, having constructed with a square hearth, a, an open-. a reduced upper aperture, d, a triangular 5 ing, a, in front the Width of the said hearthfa damper, E, journaled beneath said aperture central depression, B,in said hearth, provided d, a draft-pipe, E, a spring-bracket, H, at- 20 with an aperture, d, a tuyere-iron, D, secured tached to said iron, a slide, H, supported beneath said hearth, provided with a trianby said bracket, and means for operating said gular damper, E, and a base portion, 0, havdamper and slide, substantially as shown and :0 ing an open-draft aperture, b, in the front described.

thereof, substantially as herein set forth. MICHAEL EHRGOTT.
